Fig. 6. Effect of the amino acid composition of xylem and phloem saps on Xoo biofilm formation (A) and cell growth (B). The amino acid mixtures, which were prepared according to previous studies on xylem sap (shown as A.A. in xylem) and phloem sap (shown as A.A. in phloem), substituted the equivalent amino acids in the XOM2 medium. Data represent mean ± standard deviation from at least 6 independent experiments. The mean values showing a statistically significant difference in comparison with the control value of XOM2 medium were denoted by * (p < 0.05).
